Full Blank screen when opening new tab or webpage Does this intermittently, at least once per day. Recovery is to clear all active apps from memory, then reopen Firefox; previouse tabs are present.

No relation to number of tabs open or number of other apps open.
This problem has persisted for at least 2 FF build updates.
 It is NOT A MEMORY ISSUE, I checked last failure

3.8gb in use out of 8gb!

Using Android 13. Firefox: 139.0.4 (Build #2016095887), hg-3825afc77e5b+ GV: 139.0.4-20250609112858 AS: 139

Firefox lets me build elaborate hierarchies of bookmarks, just as a modern file system lets me build elaborate hierarchies of files. Once a bookmark exists, though, I can't find a way to tell what folder it's in. In contrast, once a file exists, it's easy to tell what folder it's in. In Windows, for example, I open a File Explorer window and search for the file by name, then right-click>Open file location to open the folder that contains the file. File Explorer's address bar shows the whole path to the folder.

If I find a bookmark through the Bookmarks>Manage Bookmarks window's search box, the window gives no clue to where the bookmark is. If I display its properties with Bookmarks>Edit Bookmark, it shows what folder the bookmark is in, but it gives no clue to where that folder is. If the folder's name is unique, an I created it, I can probably figure out where it is. But if the name is something generic like Pending, it's hopeless. I could have 193 Pending folders in different places.

Is there any way to find a Firefox bookmark's location?

Again ONLY in FF harbor freight search function breaks when entering a search.

Yes, please don't give me the MS ctrl-alt-del type of response about cookies.... That was done many times before posting this. The website works fine in Brave. MS Edge well, let's not speak of it in public company shall we.

So, now what the heck is happening to FF???? I have contacted HF three times and they referred me to use other browsers other than FF. No, I DO NOT have multiple extensions nor themes. FF is bare bones but for uBlock. Hardware acceleration is off and MS Clear type is on. Anybody wanna fess up, who broke this????

Free youtube downloader wants my age from Firefox to download popular music videos. I am logged in to FireFox and Free YouTube downloader identifies FireFox as my default browser.

This is really an error for Free YouTube Downloader to correct, but many FireFox users must have solved this already. Any advice?

Thank you!

Google suggestion in Firefox's address bar keep showing Japanese suggestions even though I chose English and Canada as language and location with my google account.

I use same google account with google chrome, but google chrome doesn't show Japanese suggestion.

As for setting on Firefox, I unticked other than "show search suggestions".

How do I resolve it?

Thank you.

My Win10 & Win11 pc's updated to this version and they all have the same problem: The bookmarks have disappeared. Including my pinned bookmarks on FF's opening page.

I also just noticed that there are no "toolbar items".

Hello

Last few days been getting .....................

Not all the time but getting more frequent

Any ideas

As the question stated I have navigated to my mozilla profile folder, ( C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\pw1dnvcy.default-release ) but there is no file called persdict.dat. I have ensured all file name extensions are visible, & none are hidden in windows file explorer (Win 10). I am at al loss I cannot figure this out.

I understand that Firefox relies on both intermediate and root CA certificates for verifying add-on signatures. There was a recent incident where a root certificate expired on March 14, 2025, as noted in the following article: https://support.mozilla.org/en-US/kb/root-certificate-expiration

Could you please let me know the latest validity period (expiration date) of the root and intermediate certificates currently used for add-on signature verification in the latest version of Firefox (139.0.4)? I understand the certificates involved may vary depending on the add-on, but I would like to confirm this specifically for the following add-on:

Thank you in advance for your assistance.

Mailfence.com is my email provider. I've been with them for years. Two weeks ago I am suddenly unable to connect with the website. My ISP is Comcast. My next door neighbor also uses Comcast. He can get to mailfence.com just fine. Can you please help with this issue. Comcast has declined to provide any help. Thanks.........Bob Horning

For the past 2 days, Facebook won't load when I try to change my page to another (just switching between accounts). It acts like it is changing or loading, and then I just get nothing. I have done all of the things that are requested from clearing my cache, browsing data, restarting, etc. Nothing is working. I've attached a picture of my screen of I receive when I try to change pages - the big F. LOL Facebook on my phone works fine. I've tried also turning off my VPN and it doesn't load.

I've also had issues with my Xfinity email loading unless I turn off my VPN.

So what is going on?

Sending this using Safari because Firefox is totally messed up. Firefox 115.24.0esr (64-bit) OSX 10.13.6 High Sierra 2011 Mac Power Book (MPB) with 16 GB RAM. Verizon DSL line, download speed tests from 10-14 Gb/sec but Latency is always 400-900+ msec. No way to measure Jitter with speedtests that will run on my older system, or Bufferbloat now that DSLreports has gone dark.

I want a tool that will allow me to see all the attempts to connect, and packets/traffic, to see it its my old computer going bad, Firefox, the wireless or wired connection to the DSL modem/router, or the DLS modem/router itself, such as a problem with reaching the Domain Name Server (DNS) etc.

I can access the DSL modem/router in the browser, but there isn't much documentation. Its made by Actiontec but customized firmware for Verizon.

The problem persists whether I am using wifi or an Ethernet cable.

My wifes 2010 MBP computer with 8GB RAM using about 6.4GB, running High Sierra and Firefox 115.24.0 (esr) seems not to have the problem at all.

Firefox will show something in the lower left corner, "connecting to..." or "loading..." etc. It can stall with either status.

Search engines would be StartPage or DuckDuckgo. With DDgo, sometimes it just spins forever, but if I click on the URL bar, it drops down another line with the same URL and "--Visit" appended. Sometimes that will load, but seems random.

Some URLs / links open in a few seconds, some spin forever.

I first called Verizon Tech support on May22 about problems (see full exchange of repeated calls & new trouble tickets below). I think, IIRC, this happens to be shortly after I upgraded my Firefox version. They have admitted to PINGs not returning, packet loss, no excuse for the Latency.

I do have a lot of pages/tabs open; Activity Monitor says my memory use is about 14GB, but the Memory Pressure stays low in the green. I also run Thunderbird, TextEdit, maybe Adobe Reader and Excel. But even when I close everything else, the non-loading issue persists. When I shut down Firefox, the memory pressure can go into the red and take a very long time (so I always shut down all other apps first). A recent shutdown stalled & I ended up losing many open pages/tabs, but even the slimmed down load has the same problem.

I have shut off the AddOn NoScript, but the problem persists.

When I go to taobao.com, the Chinese text on the product couldn't display normally. Some of the Chinese text are showing normally but some are not.

Hii. Amazing browser tho, whenever i pin something on top or chuck it into essentials - when i close that tab - it disappears (and reappears on browser restart) - i could not locate any setting pertaining to essentials that would stop that behavior (ideally when i close the pinned/essential tab i would love it to stay there as a bookmark - anyone know of a way to achieve this?

I'm using Google Docs in Firefox. Every time I right click and then click paste I get a message explaining that Firefox is incompetent and I need to hook my keyboard up to my tablet and use Ctrl + V. And tap/clicking Edit > paste won't work either. I use a mouse with my tablet, but not a keyboard.

How to I get FireFox to allow me to use Right Click or at the very least Edit > paste? Even Opera Browser can paste in a Google Doc.
